Audio Metadata Library

A tiny (2.1K gzipped) library to extract metadata from audio files.

Features

• Extracts ID3v1, ID3v2, and Vorbis comments (i.e. metadata in OGG containers)
• Supports extraction of common metadata fields:
  • title
  • artist
  • composer
  • album
  • year
  • tracknumber
  • track
  • encoder

Usage

1. Install using NPM: npm install audio-metadata or npm install -g audio-metadata to use from the shell.
2. Load in browser: <script type="text/javascript" src="audio-metadata.min.js"></script> and define the AudioMetadata global variable.

Shell

  This help
--type, -t <type>
  One of "id3v1", "id3v2" or "ogg"
--chunk-size, -c <size>
  Read the file in chunks of <size>; default is 512

audio-metadata -t id3v2 -c 100 -q 300 keepitoffmy.wav

Browser

This library has been tested on current versions of Firefox and Chrome. IE might work, since it apparently supports ArrayBuffer. Safari/Opera are probably okayish since they're webkit. Your mileage may vary.

Note: This tool is still under development.
